[0010] By adopting the above technical scheme, on the one hand, the shaft guard can prevent the operator from contacting the rotating parts, reducing the risk of accidental injury; on the other hand, the stirring shaft is protected from the influence of external dust, moisture and other pollutants, keeping the inside clean and prolonging the service life of the equipment.

[0011] Optionally, a plurality of observation holes are formed in the shaft guard.

[0012] By adopting the above technical scheme, the observation holes allow the operator to check the working state of the stirring shaft without opening the shaft guard, and potential problems can be found in time.

[0013] Optionally, at least two mounting holes are formed on both sides of the shaft guard, and a bolt is threaded into each mounting hole and is screwed to the outer side wall of the rack.

[0014] By adopting the above technical scheme, the plurality of mounting holes and bolts ensure that the shaft guard is firmly fixed on the rack, avoiding loosening due to vibration or impact, and the standardized mounting hole and bolt design simplifies the disassembly and assembly process, facilitating quick replacement or maintenance.

[0015] Optionally, the speed reducer is fixedly connected to the rack by bolts.

[0016] By adopting the above technical scheme, the bolt-fixed speed reducer enhances the stability of the entire system, ensuring smooth operation under high load, and when the speed reducer needs to be repaired or replaced, it can be easily removed by loosening the bolts, simplifying the maintenance process.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. By using a speed reducer instead of a traditional belt pulley transmission, energy loss is reduced and transmission efficiency is improved.

[0026] The embodiments of the present application disclose an adjustable speed mixer. Referring to Figure 1 , comprising a frame 1, two bearing seats 7 are installed on the frame 1, and a stirring shaft 2 is rotatably connected to the two bearing seats 7. One end of the frame 1 is provided with a drive motor 3 for driving the stirring shaft 2 to rotate, and a speed reducer 4 is installed between the drive motor 3 and the stirring shaft 2.

[0027] Referring to Figure 1 , the speed reducer 4 is fixedly connected to the frame 1 by bolts. The bolted speed reducer 4 enhances the stability of the entire system, ensures smooth operation under high load, and when the speed reducer 4 needs to be repaired or replaced, it can be easily removed by loosening the bolts, simplifying the maintenance process.

[0028] Referring to Figure 1The input shaft of the speed reducer 4 is fixedly connected with the driving motor 3, and the output shaft of the speed reducer 4 is fixedly connected with the stirring shaft 2. Three paddles 21 are fixedly installed on the stirring shaft 2 in a circumferential interval. The speed reducer 4 is provided with a shift lever 41 for adjusting the speed reduction ratio of the speed reducer 4. The speed reducer 4 internally contains multiple gear sets, each of which provides a different transmission ratio to achieve different output speeds. The shift lever 41 is provided with a sliding gear that can slide along the shaft to engage or disengage with other gears. The shift lever 41 controls the position of the sliding gear through a connecting rod and a shift fork to select different gear combinations and thus achieve different speed reduction ratios.

[0030] Referring to Figure 1 A plurality of observation holes 81 are formed in the axle guard 8. The observation holes 81 allow the operator to check the working state of the stirring shaft 2 without opening the axle guard 8, and discover potential problems in a timely manner.

[0031] Referring to Figure 1 Two mounting holes 82 are formed on both sides of the axle guard 8, and a bolt is threaded into each mounting hole 82 and connected with the outer side wall of the frame 1. The multiple mounting holes 82 and bolts ensure that the axle guard 8 is firmly fixed to the frame 1, avoiding loosening due to vibration or impact. The standardized mounting holes 82 and bolts simplify the disassembly and assembly process, facilitating quick replacement or maintenance.

[0032] The implementation principle of the adjustable speed mixer according to an embodiment of the present application is as follows: by using a speed reducer 4 instead of a traditional belt pulley drive, energy loss is reduced and transmission efficiency is improved.
